P-chlorophenylhydrazine synthesis method

The invention discloses a p-chlorophenylhydrazine synthesis method. The technical scheme comprises the following steps: reacting sodium hypochlorite and p-chloroaniline to prepare p-chlorphenyl monochloroamine, and reacting the p-chlorphenyl monochloroamine and ammonia to obtain p-chlorophenylhydrazine. Compared with the traditional diazo-reaction process for preparing p-chlorophenylhydrazine, the method disclosed by the invention has the advantages of mild reaction conditions, low requirements for equipment, less reaction steps, simple synthesis method, low by-product and wastewater output, low energy consumption, high yield and low production cost, thereby being an energy-saving environment-friendly new process.
